ARTHUR F, H. HEAD, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE J. G. BRILL 00., OF PHILADELPHIA. PENNSYLVANIA. A CORPORATION OF PENNSYLVANIA.

SCRAPER FOR SWEEPERS.

"of Philadelphia, and State of Pennsylvania,

have invented a certain new and useful Improvement in Scrapers for Sweepers, of i which the following 1s a specification.

The object of my invention is to provide a sweeper of the conventional form or any other desired form, with a suitable scraper which may be turned, raised or lowered as the conditions of its use may require, so that when in use it will throw snow in aproper manner. The turning and raising or lowering to be independent movements, so that onemay be conducted without the other. This object is accomplished by my invention,

one embodiment of which is hereinafter set forth. i v

For a more particular description of my invention, reference is to be had to the accompanying drawings, forming a part here- ;of, in which:

Figure 1 is a perspective viewof a portion of a sweeper provided with my improvement; Fig. 2 isa sectional view of my im- 1 proved mechanism; Fig. 3 is a side elevation of the same; and Fig. 4 is a plan view of the structure shown in Fig. 3.

Throughout the various views of the drawings, similar reference characters designate similar parts. I

A sweeper lprovided with my improvement hasthe usual cab 2, the platform 3, frame 4:, brushes 5 and their mountings, running gear 6, and other incidental parts, not shown, which may be of any conventional or desirediform. As these parts form no part of my invention, it is unnecessary to describe them further.

My improved scraper 7 is mounted on a suitable shaft 8 which is controlled by a mechanism, described below, so that the scraper may be raised or lowered or splayed so as to properly scrape and throw the snow on which it is operated. The plate or scraper 7 is preferably made in the shape shown or in any other desired shape and has two reinforcing strips 9 and 10, at the top and bottom respectively. These strips are secured to suitable sockets 11, an upper and a lower, which are mounted so as to fit snug on the shaft 8 .and to slide thereon, but not to turn thereon, the shaft 8 being made square in Specification of Letters Patent.

cross section for this purpose. If desired,

this shaft may be given any other suitable cross section. Between the sockets 11 1s a suitable buslnng 12, in which this shaftmay slide, but ,not turn, and this bushing has a cylindrical outer face, which is journaled in asuitablc bracket 11.3, which is attached to the runnmggear (S of the sweeper. By this means. it is possible toturn the shaft 8 in the bracket 13 or to raise or lower it in said bracket. The upper end of the shaft 8 is similarly providedwith a suitable bushing 14 which ismounted so as to turn inasuitable bracket 15 which is secured in any suitable manner to the frame 4: of the sweeper.

Above the bushing 1% and resting thereon is an arm 16 which is made with a suitable perforation through which the shaft 8 passes and fits with a snug fit, so that this shaft has a Vertical movement onlywith regard to this arm 16. The ar1n16 carrles an upwardly extending pair of ears 17 mounted in any desirable way but near the shaft 8 and at its free end it is perforated so as to receive a suitable pin 18 which is adapted to fit in any of the holes 19 of the sector 20 which rests on the floor 3 of the sweeper and is secured thereto by any suitable means. The curved portion of this sector is made on the arcof a circle struck from the axis of the shaft 8. y The ends of this sectorbar are bent at 21. to raise the center above the floor. Between. the pin 18 and the brackets 17': are

sector brackets 22 which are suitably perforated at 23 for a purpose which will now be described.

The sector brackets 22 are curved, so that their perforations 23 are concentric with the perforations at the top of the cars 17 and a suitable hand lever 24; is fulcrumed 011 pin 25 in these perforations at the top of these cars 17 and between the same. free end of the hand lever 24: may be secured in any suitable position by means of a pin 26 which passes through this lever and through the perforations 23. The other end of the lever is preferably bifurcated, so as to pass on each side of the shaft 8 and just beneath a suitable pin 27, against which this lever 24; rests, so that by raising or lowering this lever, the shaft 8 is raised or lowered. The lower end of the shaft 8 has a The p similar pin 28, on which the lower bushing is raised and when the pin is lowered, the scraper is lowered. The scraper is turned about the axis of the shaft 8 by removing the pin 18 and then shifting the arm 16 either directly or indirectly through the lever 24; until the desired splay is reached and then the arm 16 is placed over the suitable hole and the pin 18 restored. By so doing, the scraper 7 may be given the proper splay at the proper elevation. It will be noted that this scraper is to be used in connection with the brushes not shown in Fig. 1 and that the raising and turning are independent movements. By further reference to this figure, it is obvious that a casing 29 may be employed to cover some of the elements, such as the lever and the pin 27 on the upper end of the shaft 8.

Wlnle I have shown and described one embodiment of my invention, it is obvious that it is not restricted thereto, but is broad enough to cover all structures that come within the scope of the annexed claims.

Having thus described my invention, what I claim is: A

1. In a machine of the class described a vertical shaft, bearings for said shaft, a scraper blade mounted on said shaft, means to rotate said shaft and scraper blade comprising a lever slidably mounted near the upper endof said shaft, and means to raise Or lower said shaft and scraper blade comprising a bell crank lever fulcrumed on said first-named lever. I

:2. In a machine of the class described, a car, a vertical shaft, bearings for said shaft on the side of said car, a scraper blade mounted on said shaft, means to rotate said shaft and scraper blade comprising a lever slidably mounted near the upper end of said shaft, and means to raise or lower said shaft and scraper blade comprising a bell crank lever fulcrumed 011 sa1d first-named lever.

3. In a machine of the class described, a vertical shaft disposed outside a car, bearings for said shaft also outside the car and a scraper blade mounted on the shaft, means within the car comprising a slidably mounted lever for rotating said shaft and scraper blade, and independent means within the car for raising and lowering said shaft and scraper blade.

4. In a machine of the class described, a vertical shaft disposed outside a car, bearings for said shaft also outside the car and a scraper blade mounted on the shaft, means within the car comprising a slidably mounted lever for rotating said shaft and scraper blade, and independent means within the car for raising and lowering said shaft and scraper blade, said raising and lowering means comprising a bell crank lever fulcrumed upon the first-named lever.

5. In a machine of the class described, a

scraper, reinforcements secured thereto, sockets secured to said reinforcements, a vertically disposed shaft slidably mounted in said sockets, a pin supporting one of said sockets from said shaft, bushings mounted 011 said shaft and adapted to turn with the same, bearings in which said bushings are mounted and means for mounting. said bearings, an arm slidably mounted on said shaft and adapted to swing the same about its axis, brackets and ears mounted onsaid arm, and a lever pivoted in said ears and secured in any of several positions between said brackets, said lever operating with said shaft for raising. and lowering the same.
